Because it’s so hard to convey sarcasm in email/IM/SMS/etc., a firm has created a “SarcMarc”, or sarcasm punctuation mark.

Paul Sak of the firm said that the new punctuation mark was not a gimmick and had serious potential applications, such as allowing deaf people to pick up sarcasm in subtitles.

They want $1.99 for the little mark.  Seems like the irony mark would work just as well (and is free).
